What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
The persistent inefficiency of landfill operations and plastic waste management in South Africa has intensified environmental contamination, underscoring the urgent need for innovative bioremediation strategies. This study aimed to identify and evaluate fungal isolates from landfill soils for their ability to biodegrade polyethylene (PE), thereby contributing to sustainable plastic waste management solutions. A total of eighteen fungal isolates were recovered from local landfill soils using plastic-enriched soil dilution techniques. These isolates were screened for PE biodegradation by incubating pre-weighed polyethylene strips with each fungal culture for 45 days at ambient temperature. Biodegradation efficiency was assessed through gravimetric weight loss, while structural alterations in the polymer matrix were examined using fourier transform infrared (FTIR) spectroscopy and scanning electron microscopy (SEM). Several isolates demonstrated significant PE degradation, including the novel PE degraders Arthrographis kalrae SP5INT, Lecanicillium coprophilum SP7MK, and Didymosphaeria variabile SP11INT, reported here for the first time. Penicillium chrysogenum SP17MK and Engyodontium album SP3MK showed the highest degradation rates, achieving over 20% weight loss. FTIR analysis revealed the appearance of carbonyl groups (~ 1700 cm⁻
